Default Lights for a planted tank
In article ink.net,
says...
I assume you plan to do CO2 injection?

I have a question about the lights. I have a 75 gallon and would like
to start adding plants. I can get either T12 dual shoplights, or T8
dual shoplights for $7 a piece. Each T12 is 40 watts so, for 3
shoplights that would provide 240 watts, which is a little over 3 watts
per gallon. But the T8's are only 32 watts each which would only be 192
watts or about 2 1/2 watts per gallon. I've also seen fewer variety of
bulbs for the T8's. Which would you prefer?


Actually I don't plan on doing injection. At least not at the start.

Thanks!
Greg
